Random I/O with heavy write intensive sql applicatio
Posted: Tue Mar 13, 2012 9:06 pm
We currently have a T800 with 4 controllers hosting a SAS hosted web application with SQL backend and about 30 VMs. Performance has been great. We are now looking to add another 4 controllers and many drives to add load of a write intensive (75% writes to reads) SAAS application after a merger. I have heard a few things about 3Par not handling heavy write performance and unpredictable load as well as other SANs such as VMaxe even with Adaptive Optimization since it is not real time. Anyone have thoughts or experiences to share here?
